type in which the watch incci tamed in a case having a hinged example, a hunter case.

A further object of the invention is to provide a Watch having a body portion and a .iinged lid portion, with means vherehy clos- 115 ing movement of the lid rc-Winds the winding spring of the Watch mechanism contained in the case.

A still further object is to provide a watch in which the mechanism is contained in a case having a hinged lid, with a lever arm associated with the Winding mechanism of the Watch, and bearing upon the interior surface of the lid, that when the lid is closed down upon the body oi? the case, the winding mechanism is operated to re-wind the spring.

In order that the invention may be clearly und rstooo and readily carried into practice, I have appended hereto one sheet of drawings, illustrating the same, wherein Figure 1 show a watch according to the invention partly in section, seen from the re Wind ng l'nechanism side, with the lid oi? he ease open.

Figure 2 is plan View oi. the watch when closed, part of the case being cut away and the re-winding mechanism being shown in section.

The watch comprises a case of square shape with the corners cut oil, comprising a body portion 1 and a lid 2, the latter being connected to the body by means of a hinge 3. In the body 1 is contained a Watch movement 4-, oi round shape, possessing a direct acting pull-out mechan sm for re-winding and hand i This mechan'sin is operated by the usual re-winding spindle 5 operating in lrnovvn manner the pivoted lever 6 and the re-winding pinion 7.

Further, according to this invention, the spindle 5 automatically receives a movement of rotation in the re-winding direction of the driving spring of the movement, each time the hinged lid 2 is closed down upon the body 1. To this end, the outer end of the spindle 5 is squared and hashcyed thereon a ATES l" SCHILD, OF GRENCHEN, SVfZTZll-ltLAI-TD WAT CH 504,537, and in Switzerland. January 11, 1930.

pinion 9, and has ixed thereon, with the aid a screw 10, a head 11 which serves for operating the spindle when it is desired to set the hands of the watch. i

The pinion 9 meshes u at rear 12 solid 13 whicn meshes with a o freely about its own 1 its pinion 13 is simiidge 16 by means of n the squared part of are adjusted and maintained and a lever 19 which rries at its f ee end a roller 21. On the cove i8 is wound coil spring 22, one end t which bears a ainst the body 1, while the A "Ow ther end nears laterally against the lever 5 'i. he spring 22, being under torsion, continually acts on the lever 19 and tends to rotate it, the same s the spindle 15, in the contrary direction to the direction of rota tion indicated by the arrow Figure 1.

W ien the case is closed the body 1 and the lid 2 are retained in en 'agement by means of the usual c sing catch, Which catch is not shown in the drawing. In this position, the lever 19 is lodged in a recess formed in the interior edge of the body 1 and bears, with its roller 21, under the action of the distorted spring 22, against the flat interior edge of the lid it follows that the lid 2 of the case opens under the action of the lever 19 operated by the spring 2, as soon as the catch of the case is operated. The movement of rotation oi the spindle 15 is then transn'iitted to the re-winding spindle 5, through the intermediary of the train of gearing i l, 13, and 9, but it noperative on the drivin spring oi the movement, is usual, when the spindle 5 receives rotary movement in the direction opposite to that coresponding to re-winding.

(in the other sand, it the lid is closed down with the hand, it pushes back tne lever 19 into its initial position and all the movable parts 15, let, i3, 12, 9 as well as the re-winding spindle 5, rotate in a direction contrary to that which previously occurred, i. e. in the while the pinion direction for re-winding the driving spring, so that the later is rewound to a certain extent each time the lid is closed.

Resetting to time of the hands of the watch is effected in the usual manner, with the aid of the head ll. If a pull is exerted on the head ll, the re-winding spindle 5 is displaced axially and outwardly, and produces clutching in of the resetting mechanism, 9 is disengaged from the gear 12. This pinion 9 meshes again with the gear 12 when the re-winding spindle is pushed back into its initial position.

In the present example, the lever 19 carries a roller 21 which rolls on the interior of the lid. However, this roller is not indispensable, for the end of the lever could without disadvantage directly bear and slide on the edge of the lid.

Various modifications may be made without departing from the invention. For example, the lever 19 may be connected directly to the re-winding spindle 5 instead of being mounted on an auxiliary re-winding spindle. It might even be connected to a re-winding pinion idly mounted on the spindle 5. As to the spring 22, it could be replaced by any other hind of return spring, even by a torsion spring mounted in the hinge 3. In this later case the end of the lever 19 must necessarily be positively connected to the lid 2.

What I claim is l. A watch comprising a case body, a watch movement in said case body, a lid hinged to said case body, a main winding spindle for the spring of said watch movement, an auxiliary winding spindle, gearing between said auxiliary winding spindle anc said main winding spindle, and a lever arm carried by said auxiliary spindle, the tree end'ot said lever arm bearing against the interior surface oi said lid so as to be given an arcuate movement when said lid is closed down upon said case body, whereby said spindles are rotated.

2. A watch comprising a case body, a Watch movement in said case body, a lid hinged to said case body, a main winding spindle for the spring of said watch movement, a pinion on said main spindle, an auxiliary winding spindle, a. pinion on said auxiliary spindle, an idle gear interposed between said two pinions, and a lever arm carried by said auxiliary I spindle, he free end of said lever arm bearing against the interior surface of said lid so as to be given an arcuate movement when said lid is closed down upon said case body, where by said spindles are rotated.

3. A watch comprising a case body, a watch movement in said case body, a lid hinged to said case body, a main winding spindle for the spring of said watch movement, an auxiliary winding spindle, gearing between said auxiliary winding spindle and said main winding spindle, a lever arm carried by said auxiliary spindle, and a roller carried by the free end of said lever which bears against the interior surface of said lid, whereby on closing movement of said lid, said lever is given an arcuate movement during which it rotates said spindles and re-winds the spring or" the watch movement.

4. A watch comprising a case body, a watch movement in said case body, a lid hinged to said case body, a main winding spindle for the spring of said watch movement, an auxiliary winding spindle, gearing between said auxiliary winding spindle and said main winding spindle, a lever arm carried by said auxiliary spindle, the free end of said lever arm bearing against the interior surface of said lid, and spring means tending to hold the lid in open position and the lever in raised position, whereby on closing movement of said lid, said lever is given an arcuate moveme t during which it rotates said spindles and re-winds the spring of the watch movement.

5. A watch comprising a case body, a watch movement in said case body, a lid hinged to said case body, a main winding spindle for the spring of said watch movement an auxiliary winding spindle, gearing between said auxiliary winding spindle and said main winding spindle, a lever arm carried by said auxiliary spindle, the free end of said lever arm bearing against the interior surface of said'lid, and spring means acting on said lever arm to hold it in contact with the interior of the lid, whereby on closing movement of said lid, said lever is given an arcuate movement during which it rotates said spindles and re-winds the spring of the watch movement.
